USDA confirmed New World screwworm in a dog in Cochise County, Arizona, near the Mexican border, the state's first case and the third state with an animal infection after Texas and New Mexico. Officials set a 20-kilometer infested zone with animal movement controls, expanded surveillance and trapping, and released sterile flies.
Confirmed spread into a third U.S. state raises the risk of livestock movement restrictions and herd losses, tightening cattle supply and supporting feeder and live cattle prices while adding to demand uncertainty for feed.
After 148 past bullish disease events, Live Cattle moved a median +0.4% over 5 sessions (62% higher; middle half -0.5% to +1.2%), and +1.4% over 20.
After 122 past bullish disease events, Feeder Cattle moved a median +0.4% over 5 sessions (60% higher; middle half -1.0% to +1.6%), and +2.0% over 20.
